Stroking...

I have a couple of questions about stroking a block. I have been looking into building a 408 block. I don't think that there is even a question of whether or not the cast iron block is a better than aluminium. Yeah the block weighs more but the strenght is there. I am still trying to decide whether or not that a power adder might be the next step. I'll have to see what the 408 feels like? I know the clutch and the 10-bolt will have to go. Regarding the 408... Are there different combos of bore and stroke sizes in the 408 cid? If there are which one is most reliable? I saw that Texas Speed is selling bare blocks for ~$600 and thought that it may be more fun to have more displacement (no replacement for) rather than putting a D-1SC on a 346 cid.

Doug, a properly built 402 LS2 aluminum is good for 1000+ hp! Don't bother putting a anchor in the front of your car unless you plan to make 1500hp! Its just not needed. A 402 with AFR 225 heads will get you 525rwhp... You could always gap the rings a little extra for a 100 or 150 shot... But I'll tell you right now, 525rw is lots for a streetcar!!!
